In using scales such as above described the section of the scale; Fig. t3 is an enlarged commodity whose weight is to be ascer- 0 front elevation of the indieaing ortion of tained is. placed upon the platform in its the scale with the weight taken (at and applied to-the movable tare indicating having been first ascertained or being ember; Fig, dis asectional viewon astill already known, the corresponding numeral larder scale taken on line 44 of Fig. 3; on the plate I isisingled out and the net the beam receptacleand, the weight of the receptacle journal in suitable hearings on the sill of series of numerals take the place of those on weight read from the series in line with such numeral, the beer being guided of course by where the reading line f cuts such series of net weight numerals or grzuluntions.

Passing now to the meansforrnroving out the present invention, there is arranged along the lower side of the sight opening an additional )latc J normally lying Ilat but adapted to e turned up lo expose its own series of tare weight numerals and conceal those on the plate 'I as shown in Fig. 3. Said plate J has trunnions at its end whicl'i the sight opening and one of these trunnions j extends out through the side of the casing I where there is secured to it a weighted arm J adapted to normally hold the plate lying flat, as shown in Fig. 5.

A weight M, Fig. 2, hangs normallt from a hook m on the plat-form. When the tare eapaci y of the scale is to be increased be- Vund tc range of numerals on the plate I, said weight is taken off the hook and applied to a hook j which is secured to the trunnion j and projects oppositely to the weighted arm J. The application of this weight obviously rocks the-plate J to an upright position such as shown in Fig. 3 making its the fixed plate I in similhr relation to the several series of net weight numerals on the drum. Of course the removal of the Weight M. from the hook m reduces thecounterbalanee to the pendulum and theweighted outer end ofthe beam and this is deslgned to be in degree proportionate to or cor spending with the advance in the t e weight indication. Thus, with the remov l of said weight from the hook m the eylin r turns backward an extentwhich provides for two pounds of weight being sustained upon the platform before the cylinder agaln indicates zero, and the several tare. weight indications "on the plate J are respectively two pounds in excess of the correspor'idin tare weightindic'ations'on the fixed plate It will be obvious that with the weight M removed from the hook m and applied to the hook j, the scale may be used int-he same manner as before described but will be in condition to take care of tare through an advancedran e. i Thus it will be seen that the above described construction is well adapted to fulfil the object primarily stated. At the same time it willbe understood that tho'construction here-shown and described is susceptible of modification within the scope of the invention. V

What is claimed is: 1.. In a. weighing scale the combination of a movable indicating. member bearing several series of net weightiniiications, and means bear-ing a pluralityofseries of tare weight indications; with provisions for causing one series to simplant the other in registering relationshi to the net weight indications.

'2. In a weighing scale the combination of a. movable indicatingmember bearing severa] series of net weight indications, a fixed uirhhcarip a series of tare indications registering Wu 1 the several series of net wmght indications respectively, and a movable .inemhcr also hear ng a-series of tare indications but re nesenting a continuation 01 those on the fixed part, said movable memher ad'a ited when moved from normal to display a. s series of hire indications in re istry wit 'the several series of net wcig t indications and conceal the series of tare weight indications on the fixed part.

5. In a. wei hing scale the combination of a movable'in icating member bearing several series of net weight indications a fixed .part bearing a 'fries of ta-re indications registering with t eseveral series of net weight indications respectively, a 'hiovahlc member also bearing a series of taro indications but representing a continuation of those on the fixed part, said movable. mem
